BIOENRAIZADORES NO TRATAMENTO DE SEMENTES DE SOJA E ERVILHA

Abstract

Seed treatment has proven to be essential for the success of a plantation and can be carried out with fungicides, insecticides and nematicides, however products that alter plant growth and development, such as plant growth regulators and micronutrients, can be used in seed treatment. (HENNING, 2005). Therefore, the objective of this work was to evaluate the effects of treating seeds of soybean cultivar NEO680 IPRO and pea cultivar GALLANT with biorooters based on hormones and nutrient complexes on the initial development of the plants. The experiment was carried out at the Instituto Federal Goiano - Campus Cristalina, in a greenhouse during the agricultural years of 2021/2022. The experimental design used was randomized blocks, with four treatments and five replications. The treatments were composed of: control (water only), Forth® Rooter composed of potassium oxide 5.00%, nitrogen 2.80%, phosphorus 5.00%, sulfur 3.43%, boron 0.25%, molybdenum : 3.0%, zinc 3.0%, carbon 6.42% seaweed extract (Ascophyllum nodosum) 15%, Stimulate® Cinetin 0.09g/L, gibberellic acid 0.05g/L and 4-indole3- acid ibultiric and FertGaia® Rooter composed of potassium oxide 5.00%, nitrogen 5.0%, phosphorus 5.00%, sulfur 0.08%, boron 0.25%, molybdenum: 1.5%, zinc 1.5 %, cobalt 0.15% carbon 6.70%, in seed treatment for soybean and pea crops, using 100% of the dose recommended by the manufacturer. The parameters evaluated were: plant height (cm), stem diameter (cm), number of leaves per plant, root length (cm), dry matter mass of the aerial part (leaves and stem) (g) and roots (g) at 7, 14,21 and 28 days after emergence. The results obtained by the biostimulants tested did not influence the growth and initial development of soybean and pea plants.
